Application le .Tim-e 15,

To all 'wh-omit may coman:

Be it lmownthut I, Geenen B. JAGKS01- 1, a. citizen of the United States, and a resi- .clentnof'iVestminsten Caripll county, Maryland, have invented certain Improvements in l4`i'lsees, of which the following is a specitication.

My invention-relates to fusees employed as railway or ship signa-ls, orfor pyrotechnic displays. lNhen 'employed for railway purposes, the usee is usually thrown from the rear ot' a train to serve as a signal for following trains, and for such purpose it must he relztively strong. It is also desirable that one end of the sume be pointed in order that it may readily stick in the ground or in a tie. For other uses :i handle may be employed. These and other features of my invention are more fullyreferred to hereinafter, reference being had to the accompanying drawings, in which: y

Figure l, is n -view of one form of fusee mzulein accordance with my invention; Fig. 2, is an enlarged sectional View of the upper portion of the fusee shown in Fig. l.; Fig. 3,

is an enlarged sectional view of the lower portion of the 'insee shown 1n Fig. l; Figs. 4 und 5, are seetionui views illustrating cap .und head constructions for the fusee within the-scope of my invention; Fig. 6, is a plan View of Fig.l el; Figs. 7, 8 and 9, are sectional views iilustruting buse constructions within 4the seope of my invention; Fig. 10, is a sectional view on the line (n n, Fi". 2; Fig 1l, is :i similar sectional View illustrating .a modified detail of uiy invention, and Fig. 12, is a `view ou :i reduced scale `ot another form offusec within the scope of my invention.

'Fusees of the character to 'which my invention relates comprise a tubulur element u'hieh may be and usually is composed of several iuyers of paper or pastehoard, Waterproof or not, orwith a waterproof lining or insert; sneh tubes generally containing slow burning material throughout the body of the same, with u portion of quick burning material at the end having a 'Suitable ignition portion, nornmlly covered by e. suit-able cap. While the l.so-ealled paper er pasteboard tubes are required tostand a certain test Vith regard to breaking strains and are so designe Y inasmuch as `structures of this character are handlednsuellymore 'orless carelessly, it. frequently happens that 'the shells-or leesingis ni'ade'in-sueh a. manner "`insteadof@ consuming eway with the Specification of Letters Patent.

burning material, it forms a. chimney, thereby reducing the value of the illumination.

The object of my invention therefore is to provide a shell or tube for a fusee which will consume away at substantially the same rnte'as the burning material, thereby avoiding the formation of a chimney on the one hand, and on the other-hand providing a structure much stronger than the ordinary paper or pastebord tube; one that is sufficiently stiff and strong to stick in a tie when thrown from e train, and one that is relatively cheap and easy of manufacture. The shell or tube for my improved fusee is made of metal, and of a, number of metals which may be employed, I prefer to use zinc, or a suitable alloy having a large percentage of zinc, such metal in either instance having a' melting point sufficiently near the tem vperature of the burning material so that its consumption is at substantially the same rate.

In the drawings, l represents a metallicl 'tapered form at the lower end, as indicated at 2. und in such end a pointed member is l inserted, such as a nail 3,'having a head'f which lies Within the metal tube and serves to prevent the nail falling out. The nail muy be soldered to the,I tube, or the filling,

material may be packed or tamped in such.

mnner as to engage the head and hold the nailin place. lar lshell, a thx-eed 5 is formed'in the wallof thesame, which thread may receive av cap G of some suitable soft metal, or the metal of which the tube is composed'. Preferalzly the threads of the cap do not extend throughout its length so that a pocket' 7 is provided in 'the top of the-same protecting the ignition end of the fusee, which latter may be of a character such as that set forth in Patent No. 712,932. I prefer, however, to spin the end' of the tubular metal container over the ignition end of the fusee, as indicated at 8 lin Figs. 4 imdb; lenvinga small central aperture to receive an igniting substance 9. The eu'p to 'protect this igniting substance may have en ep'eturedhead 10. with a di el: l1 of `suitable paper for instance,

At the upper end of the tubi,

closing the same and protecting the igniting substance. This disk Will preferablycarry a scratching material 11a, against which the igniting substance 9 may be rubbed When the t'usee is to be put into use.

l in 'when the scratching surface is applied-to the ignit-ing substance 9. This may be accomplished by forming an annularbead or rib in 'the cap as indicated at 6,inFigs.-4 and 5.

The scratchin material should preferably'be covered i? r protection, and for this purpose I may employ a piece Yof Waxed paper, fabric, or the like, 12, one end of Whichis caught under the flange of the cap, as at 12a, While the other end may extend down the surface of the tube and be secured by paste,- as'at 13, or be partly caught be-v .Insome instances a plain slip cap may be employed instead `'olf ther screw cap,- and if frictional engagement is insulticient vto hold such slip cap, it may be held by indenting Athe Wall of the same andthe tube Where they If the cap vis of soft metal, it may be readily torn from Vthe end.

of the fusee. A,

In lieu of making the tube .Wholly of metal, it may be of Wood veneer, 'or soft paper or pulp stock, as indicated at 14, inclosed by a metal shell. I may also employ the usual Wooden block 15 at the lower end of the fusse, as shown in Fig. 6,k bored en#k tirely thro-ugh, however, and receiving a headed nail of the character illustrated in Fig. 3. Cast members of the type illustrated in Figs. 8 and 9 may also be employed for the-end of the 'fused In Fig. 8,

the member is cupped at 16, and internally threaded at 17 to receive thel threaded end of the tube, and has a pointed end 3a.k In Fig. 9, threads 17a, to'receive the end of the 'tube, are disposed externally. It will be understood, of course, that other forms of.

' vbular member it may be corrugated, as in-I dicated in Fig. 11, and the c'orrugations may extend longitudinally ,of the tubular shell,

or be disposed helically of the same.

In Fig. l2, I have shown a fusee in which both ends are spun `d'ovvn to substantially the sameextent, the .upper end having a' small aperture for the igniting substance 9 and being-threaded to receive the` cap 6, and

tially that set forth in the patent before 11e-- lferred to, oi' any other Wellknown or ap-v proved illuminating material commonly employed with fusees. f

I claim:

1. The combination, ina fusee, o-a metaL lic shell, ignitible illuminating material inclosed bysaid SheILsaid-Shell` being spun over 'the end of theillurninating materiali with a central aperture,an ignition member disposed in said aperture, the shell being threaded below its closed end, and a threaded cap 4*engaging thev threaded end of the shell.

2. The combinatiomin a usee, of a shell of metal, ignitible materia'htherein, a metal cap for said shell having a central aperture, a paper disk within said cap and expanded into the aperture ofthe same, and a protec tive covering for said cap and disk.

3. The combination, in a fusee, of a metallic shell, ignitible material therein, said overlying said ignitionineans, andA a protectivecovering for said Lip and disk.

4. The combination, in a fusee, of a metallic shell, ignitible material carriedthereby,

said shellhaving a threaded end, ignition. l

means at the 'end cf theshell, a cap threaded to tit on said ehd` and having a central aperture, 'a paper diskv inclosed by said cap and expanded into the aperture of the same, a scratching substance carried by said disk complementa-l tothe ignition means at the end of the fuses, said scratching substance being on.the'outer surface of the paper disk, and a Waterproof protective 4covering l,for said cap 'and disk. Y

In testimony whereof, I have signedmy name to this specification, in the presence oftwo subscribing' Witnesses.
